Abstract:
Objective:To explore the effects of transcutaneous electrical nerve stimulation(TENS)on knee joint pain,func-tion,muscle strength and gait in patients with knee fracture surgery.Method:Forty patients with knee fractures were divided into the control group and the experimental group,with 20 cases in each group.Strength training,joint mobilization techniques,neuromuscular electrical stimula-tion,and routine rehabilitation training were provided to the control group.The experimental group was given the same routine rehabilitation program,except the TENS intervention instead of neuromuscular electrical stimu-lation.For six weeks,each treatment was given once daily over five days.All the patients were evaluated by Visual analogue score(VAS),American hospital for special surgery knee score(HSS-KS),isometric muscle strength test and 3-D gait analysis before and after treatment.Result:There was no significant difference between the two groups in each evaluation scores before treatment(P＞0.05).HSS-KS score,peak torque per bodyweight of knee extensors and flexors under 60°/s and 180°/s,and gait parameters in both groups were significantly improved after 6 weeks of treatment,compared to those before treatment(P＜0.05).Meanwhile,the experimental group were significantly better than the control group in terms of the VAS score and HSS-KS score,peak torque/body weight(PT/BW)at 60°/s and 180°/s of knee extensors,and subparts of gait parameters(P＜0.05).Conclusion:In patients with knee fractures surgery,TENS can significantly minimize the pain,improve knee function and gait pattern,and strengthen the absolute force of knee extensors.
